Black Nucleus
Bronya Zaychik
Black Nucleus is Bronya's S-rank BIO-type Physical battlesuit from v2.2.2: a close-range cannon DPS who turns invisible with her Ultimate Evasion and QTE, hits hardest from the side or from behind, and bombards an area with her 20-hit Suppression Barrage. In her day she was the only battlesuit able to clear the Arena in 0 seconds (Marisa Impact), and she later received a PRI-ARM, Star Destroyer 19C-X, which Marisa Impact calls more of a fun upgrade than a useful one. With no Astral Ring, she is obsolete in 9.0 and only fits older content.

Stat targets
- Stigmata affixes: ATK, Crit Rate or Physical DMG
- Always cast her weapon active while invisible
- Release charged shots on the sequence change for +30% Crit Rate
Talent priority
Where to get her: Dorm Supply, War Treasury and Battle Pass; Marisa Impact advises new players against farming War Treasury battlesuits, so only invest in her if you already own her or like her playstyle.
Recommended teams
Part 1 Physical supports
Marisa Impact's standard Physical supports for Part 1 DPS: Herrscher of Rebirth for Impair and Crit, Reign Solaris for shield break, Stun Trauma and damage. No Astral Ring: older content only.
Budget Physical team
Herrscher of Sentience was the backbone of Part 1 Physical teams with her Impair (DEF reduction), and Terminal Aide 0017 is the cheaper third support. Outdated in 9.0, but fine for events and older content.
How to play
Invisibility loop
- Her Ultimate Evasion (Dimensional Interruption) makes her invisible for 6s (CD: 16s with Particle Reset, and her leader skill shortens it further). While invisible she cannot be targeted, ignores all damage and common debuffs, and moves and attacks much faster.
- Invisibility gives +35% Physical DMG (Stealth Assassination) that lasts until 2.8s after it ends. Tapping [ATK], casting a weapon skill or her Ultimate, or switching out ends invisibility, so use it to reposition before your burst.
- Her QTE (Field Suppression, on airborne or Time-Slowed enemies) slams for 3 x 320% ATK of Physical DMG and also grants 6s of invisibility.
- Field Breach: +39% Total DMG Multiplier when attacking from the side or from behind.
Charged cannon
- Her Basic ATK is a charged cannon shot (Charge: Shrapnel Shell) with 3 charge sequences; with a missile-type weapon it fires scatter shells that explode on impact.
- Release [ATK] right as a new charge sequence starts for +30% Crit Rate (Precision Charge). At SSS, releasing on the 3rd sequence adds 20% DMG and 100% Move Speed for 3s.
- Getting hit while charging forces a dodge (once every 4s) without breaking the charge.
Burst window
- Ultimate Evasion (or QTE) → invisibility, then get behind the target.
- Cast Star Destroyer 19C-X's active while still invisible: +40% Crit Rate, a 6s shorter CD, and up to 8 barrage Charged ATKs (drag the weapon button to aim over the shoulder).
- Suppression Barrage (125 SP): an immobilizing field that bombards the area for 20 x 80% ATK of Physical DMG, +100% ATK per hit with Mortar Cannon, with Ignite Trauma procs and, from SS rank, 5 Stun Trauma.
Her kit predates Astral Rings and Part 2 enemy mechanics: keep her for older content, events and nostalgia.
Strengths
- Invisibility makes her very safe: she cannot be targeted and ignores damage while it lasts.
- A strong burst window with her PRI-ARM: +40% Crit Rate and a shorter weapon CD when cast while invisible.
- Her leader skill shortens the CDs of the team's Ultimate Evasion and Perfect Defense effects.
- Easy to get: Dorm Supply, War Treasury and Battle Pass (Marisa Impact).
Weaknesses
- Obsolete: no Astral Ring, and Marisa Impact considers every War Treasury battlesuit outdated.
- Positional: her Total DMG bonus needs side or back attacks, and invisibility ends as soon as she attacks.
- Marisa Impact describes her PRI-ARM as more of a fun upgrade than a useful one.
- Several key buffs (Thermal Activation's Crit DMG, Stun Trauma on her Ultimate) need SS rank.
Notable dupes · Rank
Thermal Activation (+30% Crit DMG and bonus Fire DMG on every crit), 5 Stun Trauma after her Ultimate, and a stronger leader skill (-4.5s instead of -3.5s).
Primed Charge: releasing on the 3rd charge sequence adds 20% DMG and 100% Move Speed for 3s.
